Answer:

The correct answer is B) 1/9

Step-by-step explanation:

In order to find this answer, you need to take the fraction that answered it on the first try and subtract the number that changed their mind.

5/18 - 1/6

In order to complete this operation, you need to give them common denominators.

5/18 - 3/18 = 2/18

And we can simplify that answer.

2/18 = 1/9
